The primary advantage of monovision for the patient is freedom from reading glasses. Usually, after six to eight weeks (or even sooner), the brain will begin to alter and differentiate objects automatically, hence making it possible to have the full range of focus without corrective lenses.
Monovision seems to work best in people who do not have a strong dominance in one eye or the other. If one eye is slightly dominant, it usually is corrected for distance and the non-dominant eye is left alone, or made a little short sighted for reading. The difference in vision between the two eyes should be small or no larger than 2.0 dioptres. The larger the difference, the more ‘out-of-balance’ you will feel.
If a person has less than two diopters of myopia (long sightedness of approximately 20/100 or better), one eye can be corrected to provide good long sight, and the other eye can be left uncorrected primarily for good short sighted vision
People with greater amounts of myopia may have their dominant eye corrected for long sight, and the non-dominant eye under-corrected to provide better short sighted vision
It is surprising how many patients adapt readily and happily to this vision option. Should you initially choose monovision and subsequently become unhappy with it, you can have it undone, and your short sight eye corrected for long sight. Your two eyes will be working together again, but you will need to wear reading glasses.
